However, 25 is NOT 2/3 of the way between 16 and 32. You just have to remember that the scale is exponential, not linear. 4 2/3 stops allows 24.66 more light, and 24.66 = 25.28132..., or roughly 25. It's actually 9/16 (0.5625). Meaning that 25x less light is actually 4.5625 stops less bright, rather than 4.66 stops. Again, you're mixing linear and ...


I love photo math but that approach will drive you crazy and nothing will come of it. The Guide Number method is tried and true. Once you know the guide number for your flash or combination of flashes, you divide the subject distance into that value. Suppose the guide number is 200 and the subject is 18 feet from the camera. The math is: 200 ÷ 18 = 11. ...


No, the D3300 does not support high-speed sync, (none of the D3x00 or D5x00 bodies do) so you're limited to 1/200s and below shutter speeds. Anything faster, and you will have black bars on the image. In addition, your (one assumes Neewer) TT-560 is a manual-only flash and cannot perform TTL or HSS, which is why it's so super-cheap. It only has the ...


No, you can't. To quote from v5.0 of The Other YN-622C User Guide II, page 20: The Canon YN-622C is NOT compatible with the Nikon YN-622N. The camera codes are not the same. This actually makes sense when you consider the completely different pin/contact arrangement on the hotshoe and the inevitable differences in signal protocols. The only way I ...


This is an apparent design flaw. The YN685 is a very inexpensive superficial copy of the Canon 600EX. I wouldn't call it a "clone" as that implies more similarity than actually exists. The Canon 600EX (and prior flashes such as the 580 and 580-II) project a pattern of horizontal bars that provides a good target for the camera focusing mechanism. The ...
